COMBINED REBOUNDING, MAIN, AND TRIGGER SPRING FOR FIREARIVIS.

Application led June 13, v1916.

kactuation of the trigger mechanism, the

hammer and .the rebound of the hammer.

This increases the number of springs em ployed and considerable difficulty has arisen due to breakage and the difficulty which arises in tempering the springs so that they 1 will all have the same standard of resiliency whereby a spring which is usedto replace one which has been broken willhave the same amount of resiliency7 as the one which it replaced.

In order to overcome the above and other defects arising from springs as heretofore employed, I have devised a novel spring which has a triple function since it not only serves as the trigger spring but also as the hammer spring and it is constructed in such a manner as to control the rebound of the hammer to prevent the hammer interfering with the proper revolving of the cylinder.

IVith the above and other objects in view which will hereinafter more clearly appear in the detailed description, my invention consists of a novel main, trigger, and rebounding spring and a novel construction of hammer, trigger, and casing adapted to coperate with it.

It further consists of other novel features of construction and advantage, all as will hereinafter more clearly appear.

For the purpose of illustrating my invention, I have shown in the accompanying drawings, a typical embodiment of it which will give satisfactory and reliable results in practice, although it is to be understood that this embodiment is typical only and that the various instrumentalities of which my invention consists can be variously arranged and organized, and that lmy invention is not Specication of Letters Patent.

limited to the precise arrangement and orinstrumentalities as herein set forth.

Figure 1 represents a side elevation of a fire arm, partly in section, showing acombined main, trigger, and rebounding spring, and its adjuncts, embodying my invention, certain parts being omitted for the sake of `clearness of illustration.

Fig. 2 represents a side elevation, partly in section, and similar to Fig. 1, but showing certain of the parts in a different relation from that seen in said figure.

Fig. 3 represents a .perspective view'of the combined main, trigger and rebounding spring in detached position.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings:

l'clesignates a frame having a grasping handle 2 which is chambered as at 8, in order to receive a combined main, trigger and rebounding spring 4 embodying my invention. 5 designates a trigger which is pivotally mounted at 6 and provided, in the present instance, with a finger piece 7 pivoted to the trigger. 8 designates a pawl pivotally carried by the trigger and adapted to effect the automatic revolution of the cylinder in the usual manner. 9 designates a spring pressed cocking pawlwhich Veffects the backward movement of a hammer 10 and is pivotally mounted on the trigger 5. The rear face of the hammer 10 is provided with an inclined face or wall 12 which connects with a curved face 13 by means of a Irecess 14,. rIhe spring #l is formed from a single piece of material such as, rfor example, piano wire, one end 15 of which is adapted to be seated in a recess 16 in the lower wall of the chamber 3. The end 15 extends npwardly and then curves laterally, as at 17, and is then directed upwardly, as at 18. then laterally. as at 19` and then bends downwardly, at 20, in order to form the rebounding element 21. The spring is then curved rearwardly at 2Q and deflected `upon itself to form a coil Q3 and then curves forwardly anddownwardly, as at 24. and its free end is 4preferably flattened to form a forward terminal 25, which engages a groove or recess 26 in a rearward extension of the trigger 5.

The spring flis inserted in place so that the rear terminal 15 interlocks with the recess 1G while the forward flattened terminal 25 rests upon and interlocks with the recess 26 in the trigger. The rebounding terminal 21 is then snapped into place so that when the hammer is forward it assumes the position seen in Fig. 1 and bears against the inclined wall 12. vWhen the hammer is retracted and the sear is ready to release the hammer 10, the spring assumes the position seen in Fig. E2.

The outer end of the terminal 21 interlocks in the recess 14 and engages the walls of said recess, as will be understood by reference to Figs. 1 and 2. and owing to the l angle of the inclined face or wall 12, the

terminal will have a lever action upon the hammer and since this terminal is connected by the two spring portions 9.2 and 17, the hammer is maintained under constant tension during the act of firing and after the tiring pin 27 has engaged the cartridge, the terminal 21 will cause the rebound of the hammer away from the anvil Q8 so that the.

parts will assume the position seen in Fig. l. The firing pin 27 will be withdrawn a sufficient distance to permit the revolution of the cylinder.

In so far as I am aware, I am the irst in a device of this character to provide a tension device which maintains a constant tension on the hammer during the act of firing and it is to be understood that my claims to such features are to be interpreted with corresponding scope.

By the employment of my novel invention, I eliminate to a marked degree the breakage of the springs and owing to the novel construction of spring one is enabled to temper them in such a manner that the springs are standard and can be readily replaced by another spring of the same type without necessitating the employment of a skilled workman. It will be apparent to those skilled in this art that in accordance with my present invention, I employ a novel construction of a tension device which maintains the hammer under tension during the act of ring or, in other words, until the trigger is released for the next shot. By altering the angle of the rebounding terminal and of the inclined wall of the hammer, the

amount of rebound imparted to the hammer is correspondingly varied.

It will now be apparent that I have devised a novel and useful construction of a combined rebounding, main and trigger spring for fire arms which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and while I have, in the present instance, shown and described a preferred embodiment thereof which will be found in practice to give satisfactory and reliable results, it is to be understood that the same is susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:-

1. As a new article of manufacture, a spring consisting of an integral piece of spring wire Yhaving one end forming an abutment, its other end forming a trigger engaging portion, and having intermediate its ends a rebounding terminal.

Q. As a new article of manufacture, a single spring having a coil intermediate its ends, deflected upon itself to form a rebounding terminal, and having onev end forming an abutment, and having its other end forming a trigger engaging element.

3. In a lire arm, the combination with the housing, the hammer, and the trigger, of a single spring having one end engaging the housing, the other free end engaging the trigger, and an intermediate portion engaging the hammer.
